My ambition was to stop waiting tables. That was how I measured success: finally, I was able to stop waiting tables, and I was able to pay the rent, and that was by being a stand-up comic. Not a very good stand-up comic, but good enough to make a living.
Ambition is a dream with a V8 engine.
Being humble matters.
The fragrance of flowers spreads only in the direction of the wind. But the goodness of a person spreads in all directions.
